' CARRIER FOR BRAIDING MACHINES.

- Application filed December 31, 1924. Serial No. 759,015.

This invention relates to improvements in the construction of braidingmachine carriers and is an improvement on my earlier Patent No.1,479,397, January 1, 1924. This invention has for its object to providea carrier which is extremely light in Weight, whereby high-running speedmay be obtained, and the carrier is provided with a coiled spring actingupon the yarn tension Weight to accelerate its take-up action upon theyarn.

A further object of the invention is to form many of the operating partsof the carrier of pressed sheet metal thereby greatly reducing theweight of the carrier.

A still further object of the invention is to provide a pair ofcooperating standards on the carrier, one serving as a vertical guidefor the weight and its operating spring, and the other serving tocooperate with the first standard to provide a lateral guide for theweight and also to provide a guide for the latch, the second standardalso serving as a vertical guide for the latch lift member.

With these and other objects in view, the invention consists ofcertain'novel features of construction, as will be more fully described,and particularly'pointed out in the appended claims.

. In the accompanying drawings Figure 1 is a side elevation showing myimproved construction of carrier with a latch mounted to slide on thestandards to control the let-off action of the package.

Figure 2-is a perspective View of the ten.-

- sion weight.

Figure 3 is a perspective view of the latch and the latchlift member.

'Figure 4 is a perspective view showing a tubular core on which the yarnmass may be carried, this core being provided with a ratchet tootheddisc for engaging the latch to control the let off step by step.

- Figure 5 is a perspective view showing the weight and latch in raisedposition to permit the packagecarrier to be rotated.

, Figure 6 is a perspective view showing an auxiliary yarn packagesupport adapted to be mounted on the package spindle, the lower. discbeing toothed to engage the letoff latch and the upper disc having astop pin to engage the teeth of the usual yarn package.

- Figure 7 shows the auxiliary package support as mounted on the packagespindle and'supporting a yarn package.

It is found in practice of advantage, in some cases, to eliminate theusual pivoted stop pawl and slidably mount a let-off latch 00 on theweight and latch lift standards, whereby the latch is supported close toits engaging end to reduce the cramping action to the minimum so as toreduce the friction and wear and insure better operating results whenthe carrier is running at a high speed. It is also found in operating alatch of this character, in some instances, of advantage to provide atoothed disc on the yarn package having peripheral teeth adapted toengage this latch directly, While in other instances, it is found ofadvantage to provide an auxiliary package support, which is providedwith a dischaving teeth to engage my improved form of latch and 76 alsomeans for engaging the teeth of the usual form of package spool orbobbin having end teeth; and the following is a detailed description ofthe present embodiment of my invention showing one means so by whichthese advantageous results ma be accomplished.

With reference to the drawings, 10 designates the base of acarrier of myimproved construction, the same being provided with a hub 11 supportinga package'spindle 12 on which is mounted a yarn package 13, and asillustrated in Figures 1, 4 and 5 this package is provided with atoothed disc 14 which is mounted on the core 15 .of the spool or bobbin.The base of this carrier isprovided with two upright standards 16 and17, both of which are set on the major axis through the base which issubstantially the center line through the long dimension of thequoit-engaging portion of the carrier, thereby obviating the necessityof making right and left handed carriers. Each of these standards ispreferably of hardened steel and of small diameter with its lower endforced into the base. One of these standards 17 is of a heightconsiderably less than that of the spindle 12 andits end is reduced andbent to form an open threadguide eye 18. The other standard 16 carriesthe tension weight ormember 19 which is mountedto slide verticallythereon, the weight being preferably struck up from sheet stock having ahorizontal plate 20 with its sides 21 turned downwardly to formstop-engaging arms.

The plate 20 is provided with forwardlyprojecting fingers 22 arranged toembrace the opposite standard 17 to serve as a gu1de and preventrotation of the weight on its standard.

In order to provide an elongated bearingfor this weight on its standard,I have formed an upturned portion having its end 24: turned inwardly.This end being pierced with a hole 25 in line with the hole 26 in itsplate 20 to provide a double supporting bearing for the weight on itsstandard. This upper supportis also provided with a laterally extendinghook-shaped linger 27 to serve as a thread guide around which the yarnis looped after passing through the eye 18. From this guide it is led upthrough the open guide eye 28 in the upper end of the weight standard16.

Tension is applied to this weight by means of a light, coiledcompression spring 29, the upper end of which passes through a hole 30in the standard 16 while the lower coils are arranged to engage theinturned guide end 24: of the weight to apply the desired amount oftension thereto.

On these two standards 16 and 17 is slidably mounted a latch plate 30,the same bein provided with an inwardly extending raise% portion 31forming a. latch tooth which engages the teeth 41 of the ratchet toothedwheel 14. This projecting latch tooth is preferably formed of sheetstock from the plate, which is first turned upwardly and then outwardlyand one of the side walls of this latch is formed by turning the stockon one side straight down to form a square shoulder against whichratchet teeth ll will engage, while at the opposite side the wall isturned backward on an angle to provide an inclined face' as at 32 thuspermitting the teeth 41 to ride under this pawl when the package isturned in a backward or counter clockwise direction to take up the yarnthereon.

In some instances it-is found of advantage to form the peripheraltoothed wheel 1% on the spool or cop tube 15, which teeth are todirectly engage the latch for the purpose of controlling the. let off ofthe yarn; while in other cases instead of forming a peripheral toothedwheel on the spool or tube, I provide an auxiliary package support 33,which has two spaced discs mounted on a short sleeve 34 which is adaptedto be positioned on the package spindle, and on the lower end of thissleeve is fixed a toothed disc 35, the teeth'36 of which are adapted toengage the latch 31, while to the upper end of this sleeve is fixed aplate 37 which is provided with a pin 38 adapted to engage the end teeth39 of the ordinary package spool 40 which may rest upon it.

My improved carrier is very simple and practical in construction andefiective in its operation and by my improved constructmn the effectiveworking speed of the carrier, may be increased over that of the usualcarrier of this character.

The foregoing description is directed sole- 1y towards the constructionillustrated, but I desire it to be understood that I reserve theprivilege of resorting to all the mechanical changes to which the deviceis susceptible, the invention being defined and limited only by theterms of the appended claims.
